If itīs still shooting, I let it go all the way to the end.
But I can remenber one time I was using a german brand of ammo (very dirty) and I had to clean it during the session.
Good for me I always take my cleaning kit with me to the range.
So choose a good range bag.

I don't own anything that requires cleaning after 200 rounds to continue functioning. Typically, when I buy a new semi-auto, I will break it in, in two range sessions of about 150 to 250 rounds each, depending on how it is performing.

I did own a Ruger Security Six revolver once that would fail if I tried to fire .357 magnums after feeding it a couple of boxes of dirty .38 specials. Powder residue and melted lead would build up in the individual chambers that would not allow the .357's to fully seat, and therefore the cylinder did not rotate freely. I have not had that problem with my other revolvers, though, and I swapped the Ruger.

It would seem to me that cleaning your guns in the middle of a range seesion is a waste of time and energy since you are just going to get them dirty again. So unless you had a problem with the functioning of your firearm I see no reason.

I used to clean my guns at the range immediately after the session, just to get it done and spare wifey my stinking up the house. The range stopped allowing it though because too many people (not me included) weren't cleaning up after themselves.

No one cleaned their guns in the range proper. They allowed you to use the tables in the classroom (when the room was not in use of course). We would just lay down bunches of newspaper and it was no problem. The side door to the parking lot was right there and provided plenty of ventilation. But as is typical, guys would not bother to clean up after themselves and they had to put a stop to it.

Too bad because it was real convenient to clean and lube right after a range session, when you are already "in the mode". When I'd get home I would just load up my guns for readiness and place them in the amsec box. Done.

It depends for me. My pistols...clean them when I get home, or the first opportunity. My bolt action rifles or the AR-15, I'll run a bore snake through with a bit of CLP while the barrel is still warm. I think the fouling comes out better when it's still warm. I don't ever break down my firearms at the range to clean them.

Since I'm new to gun owership i'm praticing disassembly on my guns. I went to the range today it does get quite busy after 100 rds through the LCP I clean it for the first time and feel more confortable breaking down at home. I'm meticulous about cleaning the gun anyways. You take your time at your own pace.

Ditto. Especially since my range charges by the hour. It'd be a waste of money for cleaning it just to get it dirty again.

I buy guns that the functionality won't be affected by a few hundred arounds (or thousand even) down the tube. I typically shoot 300 rounds per visit, and clean the guns every other visit or so, unless I know it's going to be a long time before that one comes back out, I will clean it so it's not sitting dirty for months on end.
